The unusually designed Redcar signal box sits at a level crossing where West Dyke Road crosses the line. The box is an unusual design being constructed by the LNER in 1937. The box contains no frame with the semaphores having been abolished some years ago. However, it does have two interesting features. Firstly, last year Network Rail installed a, so far, unique pair of sliding barriers that cross the road from left to right locking into the vertical grey box on the end wall of the box. These replace the wheeled gates that had become notoriously unreliable, particularly in windy conditions. A video of these gates in operation can be found at....

The panel is installed in the overhanging section of the floor directly above where the warning lights are installed.
